Pulse techniques and apparatus - Part 1: Pulse terms and definitions
Provides fundamental definitions for general use in time domain pulse technology. It defines terms for pulse phenomena and characteristics which are prerequisite for efficient communication of technical information. It also defines terms for standards for methods of pulse characteristics measurement, for pulse apparatus, and for apparatus which employ pulse techniques.
Standard directions of movement for actuators which control the operation of electrical apparatus
Establishes general actuating principles for manually operated actuators forming part of the man-machine interface associated with electrical equipment.
Has the status of a basic safety publication in accordance with IEC Guide 104.
Dimensions of clevis and tongue couplings of string insulator units
Applies to string insulator units of the can and pin type and also of the long rod type as well as to the fittings used with such insulators. Defines dimensions of a series of clevis and tongue couplings to permit the assembly of insulators or fittings supplied by different manufacturers.
Note: - For co-ordination between standardized dimensions and strength classes of cap and pin type…
Third supplement: Instrumentation of gas-cooled graphite-moderated reactors
Applicable more particularly to instrumentation for gas-cooled graphite-moderated reactors, Type 1: reactors having metallic natural uranium fuel clad with magnesium alloy, and Type 2: reactors having enriched uranium oxide fuel clad with stainless steel. The IEC 60231 series of standards is no longer up-to-date and will not be revised by IEC. The standards are maintained for the time being for…
Specified the pressure and characteristics and is applicable primarily to gas as supplied by manufacterer. Is also an acceptable standard which may be invokes in subsequent stages of distribution. The characteristics include purity, water, odour, flammability and toxity and solids.
Potassium sulphate for industrial use — Determination of potassium content — Flame emission spectrop...
The principle of the method consists in dissolution of a test portion previosly ground and sifted. Acidification to pH 1 after suitable dilution and atomization of the resultant solution in the burner of a flame spectrophotometer. Determination of the potassium content by measurement of the intensity of the radiation emitted at 766 nm. Comparison with the intensity of standard potassium chloride…
Potassium hydroxide for industrial use — Determination of sodium content — Flame emission spectropho...
The method is applicable to products having sodium contents greater than 0.01 % (m/m). The principle consists in the dissolution of a test portion, followed by acidification to ph value 1. Atomization of the obtained solution in the burner of a flame spectrophotometer. Measurement of the intensity of the radiation emitted at 589 nm; comparison with the intensity obtained for standard sodium…
